Advanced Combustion/Plume Diagnostics.

Abstract

The procedures and some results of an experimental program to record and analyze the thermal radiation from particles suspended in a gaseous flow (two-phase flow) are presented in this report. Carbon particles were added to a nitrogen gas stream at 800-900 K flowing at approximately 50 m/s. Thermal radiation from these particles was observed and recorded using a scanning monochromator for the wavelength range of 1.0 to 5.5 micrometers. These spectra were corrected for instrument response and are compared to theoretical calculations which predict the infrared emission from small particles. Since these predictive calculations depend on the particle size parameter, different techniques were used to obtain the average particle size in the two-phase flow. (Author)
